1) When the electrons start flowing, the potential differences plates oppose the one of the battery. Is this because electrons are trying to go to the positive terminal but end on the plate connected to the negative terminal, due to the plate having "higher potential?"

Also when the flow stops because the potential differences of the plates matches the one of the battery because the negative plate has lower potential than the plate connected to the positive terminal?

(This would be a good time to confirm you remember how to solve for currents and resistances across circuit elements by solving for this result again). Because we have just confirmed that the voltmeter does not appreciably affect the resistance across this circuit element, the measured value will be the same as the calculated value. 10.2 CAPACITORS A pair of conductors that can hold equal but opposite charges is known as a capacitor. The conductors can be of any shape, but the most common capacitor consists of a pair of parallel metal plates; it's known as a parallel-plate capacitor: + Q - Q Notice that one plate carries a positive charge and the other plate carries an equal amount of negative charge. Therefore, the net charge on a capacitor is zero. However, whenever we talk about the "charge on a capacitor," we always mean the magnitude of charge on either plate, which is + Q In circuit diagrams, a capacitor is denoted by either of these two symbols: or The first question we'll answer is, "How do we create a charged capacitor?" Take an uncharged parallel-plate capacitor, and hook the plates to the terminals of a battery. Conduction electrons in the connecting wires will be repelled from the negative terminal and flow to one plate, while electrons from the other plate will be attracted toward the positive terminal of the battery. The current rises quickly at first, but it gradually dies out as the plates acquire charge. The plate that's connected to the positive terminal becomes positively charged, and the plate that's connected to the negative terminal becomes negatively charged. Since the positive plate has a higher potential than the negative plate, the potential difference between the plates opposes the potential difference of the battery. Charge will stop flowing when the potential difference between the plates matches the voltage of the battery because at that point the circuit will look like one that has two opposing voltage sources. electron flow this plate C becomes + + Q V - Q ma. this plate voltage of the O A
